<script>
  // 1、多行字符串
  let string1 = `Hey,
can you stop angry now?`
  console.log(string1)
  // Hey,
  // can you stop angry now?

  // 2、字符串插入变量和表达式。变量名写在 ${} 中，${} 中可以放入 JavaScript 表达式。
  let name = "Mike"
  let age = 27
  let info = `My Name is ${name},I am ${age+1} years old next year.`
  console.log(info)
  // My Name is Mike,I am 28 years old next year.

  // 3、字符串中调用函数
  function f() {
    return "have fun!"
  }
  let string2 = `Game start,${f()}`
  console.log(string2); // Game start,have fun!
</script>
